Common structural thickness configurations

Architectural applications of aluminum foam sandwich panels

Aluminum foam sandwich panels can be used for exterior cladding, ceilings, partitions and composite flooring. The face sheet, aluminum foam core, backing sheet and installation structure can be adjusted for different building locations to meet enclosure, decorative, acoustic, fire and prefabricated-construction requirements.

Aluminum foam composite exterior cladding panels

Aluminum foam sandwich panels can be used as exterior decorative and enclosure panels. While reducing facade self-weight, they can be combined with metal face sheets, surface treatments and panel-joint layouts to create different architectural effects.

Installation generally uses a dry-hanging system, connecting the panels to the building structure through hangers or framing. Undercut anchors, pressure blocks, adhesive combined with mechanical fixing, and unitized modular hoisting can also be used. The installation system can be configured according to building height, wind pressure, panel dimensions and facade design requirements.

Suitable for exterior enclosure and decorative applications in public buildings, commercial buildings, office buildings and prefabricated buildings.

Aluminum foam composite ceiling panels

Aluminum foam composite ceilings combine lightweight construction, sound absorption, fire performance and decoration. They are suitable for gymnasiums, theaters, exhibition halls, commercial spaces and other large spaces with requirements for ceiling weight and architectural acoustics.

Ceiling systems are mainly installed using modular dry-hanging methods, typically with suspension rods, framing and dedicated hangers. Depending on the ceiling design, maintenance requirements and site conditions, exposed-grid insertion, concealed-grid fixing, magnetic mounting or adhesive installation can also be used.

By adjusting panel dimensions, aluminum foam core thickness and surface finish, the system can accommodate flat ceilings, modular ceilings and building spaces requiring future maintenance access.

Aluminum foam composite partition panels

Aluminum foam composite partitions use a face sheet + aluminum foam core + backing sheet sandwich structure, combining low weight, sound absorption / noise reduction and Class A fire performance. They also provide moisture resistance, mildew resistance and formaldehyde-free characteristics for long-term indoor building use.

Installation: Light-gauge steel framing + dry assembly of composite panels. Plug-in, clip or bolt fixing can be used without masonry or extensive wet construction.

Typical applications: Office partitions, hotel room partitions, space division in commercial and public buildings, sound-absorbing walls for equipment rooms, and sound-insulating walls for data centers.

Installation advantages: Compared with traditional brick walls and gypsum-board partitions, the panels have lower self-weight and are easier to install and reconfigure on site. Modular panels can be disassembled and recycled, making them more suitable for prefabricated fit-out and space renovation.

Aluminum foam composite flooring

Aluminum foam composite flooring uses an aluminum alloy face sheet + aluminum foam core + aluminum alloy backing sheet sandwich structure. The layers can be bonded with high-strength adhesive or brazed. Double-slot, single-clip and other connection structures can be designed to combine floor rigidity, low weight and rapid assembly.

Density: About 0.1–0.4 times that of aluminum

Specific stiffness: About 1.5 times that of steel

Sound absorption coefficient: ≥0.7

Sound insulation: 20–40 dB

Installation: Interlocking / clip connection + floating installation; raised joist systems, adhesive fixing or bolt anchoring can also be used.

Application: In shopping malls, theaters, hospitals and other public buildings, aluminum foam composite flooring can be used in areas requiring lower floor weight, sound insulation, vibration damping and fire performance.

For heavy-duty, wear-resistant and industrial flooring applications, Henan Chalco can also provide industrial-grade aluminum foam composite flooring and match the panel structure and installation system to the required load, service environment and installation conditions.

Performance of Henan Chalco architectural aluminum foam sandwich panels

Henan Chalco architectural aluminum foam sandwich panels use aluminum foam as the core functional layer, combining low weight with sound absorption, sound insulation, fire resistance and low moisture absorption to meet the functional requirements of walls, ceilings, partitions and flooring.

• Noise reduction coefficient: Average 0.75, maximum 0.9. Suitable for sound-absorbing walls and ceiling systems in theaters, gymnasiums, exhibition halls and public buildings.
• Average sound insulation: 30 dB. Suitable for partitions and enclosure systems in offices, hotels, equipment rooms and data centers requiring space sound insulation.
• Fire performance: Class A+. Suitable for building walls, ceilings and partitions with higher fire-performance requirements.
• Mass moisture absorption W1: <0.1%
• Volumetric moisture absorption W2: <0.1%. Low moisture absorption helps the panels remain stable during long-term building use.
• Typical density: 0.15–0.2 g/cm³, helping reduce the self-weight of exterior cladding, ceilings, partitions and other building components.
• Compressive strength: 0.25–0.6, suitable for building applications requiring core strength and composite-structure stability.

Provide the project requirements for sound absorption, sound insulation, fire performance and weight. Henan Chalco can match the aluminum foam sandwich panel structure to the specific building application.

How do aluminum foam sandwich panels support prefabricated construction?

Factory prefabrication

Henan Chalco aluminum foam sandwich panels can be composited, cut to size, finished and prefabricated with connection details in the factory. Panel thickness, aluminum foam pore structure, surface effect and connection method can be customized according to project requirements, reducing secondary processing on site. Anhui Xinfangzun Aluminum Foam Decorative Building Materials

Dry on-site assembly

After prefabricated panels are delivered to the site, they can be installed quickly by hoisting, bolted connections or clip connections, reducing wet construction and improving installation efficiency while making later removal and maintenance easier. Anhui Xinfangzun Aluminum Foam Decorative Building Materials

Integrated assembly across multiple building systems

Aluminum foam sandwich panels can be coordinated with exterior cladding, partitions, ceilings, flooring, doors and windows so that different building areas use a unified prefabricated-construction approach. This is suitable for modular housing, public buildings, commercial offices and industrial buildings. Anhui Xinfangzun Aluminum Foam Decorative Building Materials

Architectural finishes and completed panel options

Henan Chalco architectural aluminum foam sandwich panels can retain the functional performance of the aluminum foam core while using different face materials and finished-panel forms to achieve the desired interior or exterior design effect, combining functional and decorative requirements.

Metal finishes

Aluminum or steel sheets can be used as outer face sheets for exterior cladding, ceilings, partitions and other building areas requiring a metallic appearance and durable surface. Face-sheet thickness and surface finish can be customized for the project.

PVC decorative finish

A 12 mm aluminum foam sandwich panel can use a PVC film + marine plywood / aluminum sheet + aluminum foam core + backing sheet structure, providing wood-grain, solid-color and other interior decorative effects for walls, partitions and ceilings. Anhui Xinfangzun Aluminum Foam Decorative Building Materials

Natural wood veneer

An 18 mm composite panel can add natural wood veneer over a marine plywood or aluminum-sheet composite structure to create a double-sided wood decorative effect. While retaining the aluminum foam core, the panel can integrate more naturally into hotels, offices, commercial spaces and premium interiors. Anhui Xinfangzun Aluminum Foam Decorative Building Materials

Fully edge-wrapped finished panels

Aluminum foam sandwich panels can also be manufactured as three-layer, four-layer and fully edge-wrapped composite panels for architectural projects requiring a finished panel-edge appearance and modular finished-panel effect.
